Specific structures are illustrated in FIG. 1 through FIG. 10 .

An embodiment of the disclosure provides a multifunctional suitcase. The multifunctional suitcase includes a case body 1 , a case top cover (e.g., 2 , 2 ′, or 2 ″), a telescopic pull rod (e.g., 3 , 3 ′, 3 ″) and a movable flap (e.g., 4 , 4 ′, 4 ″). The case body 1 includes a top surface 101 , a front side surface 102 and a rear side surface 103 . The case top cover (e.g., 2 , 2 ′, or 2 ″) is connected to the top surface 101 and covers at least a side of the top surface 101 facing toward the front side surface 102 . The telescopic pull rod (e.g., 3 , 3 ′, 3 ″) is disposed on the rear side surface 103 and is extendable or retractable relative to the top surface 101 . The movable flap (e.g., 4 , 4 ′, 4 ″) is rotatably connected to a front end of the case top cover (e.g., 2 , 2 ′, or 2 ″). The movable flap (e.g., 4 , 4 ′, 4 ″) is rotatable to be buckled relative to the case top cover (e.g., 2 , 2 ′, or 2 ″) or opened relative to the case top cover (e.g., 2 , 2 ′, or 2 ″) to define an accommodation space.

Specifically, reference characters 2 , 3 , and 4 refer to the case top cover, the telescopic pull rod, and the movable flap of the multifunctional suitcase illustrated in FIG. 1 through FIG. 3 , respectively. Reference characters 2 ′, 3 ′, and 4 ′ refer to the case top cover, the telescopic pull rod, and the movable flap of the multifunctional suitcase illustrated in FIG. 4 and FIG. 6 and the multifunctional suitcase illustrated in FIG. 5 , respectively. Reference characters 2 ″, 3 ″, and 4 ″ refer to the case top cover, the telescopic pull rod, and the movable flap of the multifunctional suitcase illustrated in FIG. 7 through FIG. 9 , respectively.

In the embodiment, the case top cover (e.g., 2 , 2 ′, or 2 ″) is disposed on the top surface 101 of the case body 1 . The case top cover (e.g., 2 , 2 ′, or 2 ″) enhances a bearing capacity of the top surface 101 , making a suitcase (i.e., the multifunctional suitcase) convenient for people to sit on and less prone to deformation, and people do not need to worry about the case body 1 being damaged. The movable flap (e.g., 4 , 4 ′, 4 ″) is rotatably disposed on the case top cover (e.g., 2 , 2 ′, or 2 ″). When the movable flap (e.g., 4 , 4 ′, 4 ″) is rotated to be buckled relative to the case top cover (e.g., 2 , 2 ′, or 2 ″), the movable flap (e.g., 4 , 4 ′, 4 ″) can further enhance the bearing capacity of the top surface 101 . When the movable flap (e.g., 4 , 4 ′, 4 ″) is rotated to be opened relative to the case top cover (e.g., 2 , 2 ′, or 2 ″) to define the accommodation space, it's convenient for people to place small handbags, umbrellas, snack bottles or other bags in the accommodation space at any time. The movable flap (e.g., 4 , 4 ′, 4 ″) can prevent articles from falling, allowing people to free their hands to handle other tasks during a journey, such as answering calls, checking in at station or shopping. Moreover, since the movable flap (e.g., 4 , 4 ′, 4 ″) is disposed on a top of the case body 1 , it doesn't occupy an internal accommodation space of the case body 1 , nor does it increase a volume of the case body 1 , and it doesn't affect appearance, storage, boarding or consignment of the suitcase.

In the embodiment, as illustrated in FIG. 4 and FIG. 5 , the case top cover 2 ′ can cover a whole of the top surface 101 of the case body 1 , or as illustrated in FIG. 1 and FIG. 7 , the case top cover (e.g., 2 , 2 ″) can cover a part of the top surface 101 of the case body 1 . The case top cover (e.g., 2 , 2 ′, or 2 ″) covers at least the side of the top surface 101 facing toward the front side surface 102 to ensure that the front end of the case top cover (e.g., 2 , 2 ′, or 2 ″) is disposed at the front side surface 102 . In this way, when the movable flap (e.g., 4 , 4 ′, 4 ″) is rotated to be opened relative to the case top cover (e.g., 2 , 2 ′, or 2 ″) to define the accommodation space, the movable flap (e.g., 4 , 4 ′, 4 ″) is disposed at a front side of the top of the case body 1 and the telescopic pull rod (e.g., 3 , 3 ′, 3 ″) is disposed at a rear side of the top of the case body 1 , so that a distance between the movable flap (e.g., 4 , 4 ′, 4 ″) and the telescopic pull rod (e.g., 3 , 3 ′, 3 ″) can be maximized to maximize the accommodation space.

In an embodiment, the top surface 101 is provided with a recessed part (e.g., 5 , 5 ′, 5 ″), and the case top cover (e.g., 2 , 2 ′, or 2 ″) is disposed inside the recessed part (e.g., 5 , 5 ′, 5 ″). A rotational connection position between the movable flap (e.g., 4 , 4 ′, 4 ″) and the case top cover (e.g., 2 , 2 ′, or 2 ″) is disposed in the recessed part (e.g., 5 , 5 ′, 5 ″). In this way, when the movable flap (e.g., 4 , 4 ′, 4 ″) is rotated to be buckled relative to the case top cover (e.g., 2 , 2 ′, or 2 ″), a surface of the movable flap (e.g., 4 , 4 ′, 4 ″) is flush with the case top cover (e.g., 2 , 2 ′, or 2 ″) of the suitcase, making the suitcase beautiful as a whole and the movable flap (e.g., 4 , 4 ′, 4 ″) not easy to be scratched and interfered by external objects.

Specifically, reference character 5 refers to the recessed part of the multifunctional suitcase illustrated in FIG. 1 through FIG. 3 . Reference character 5 ′ refers to the recessed part of the multifunctional suitcase illustrated in FIG. 4 and FIG. 6 and the multifunctional suitcase illustrated in FIG. 5 . Reference character 5 ″ refers to the recessed part of the multifunctional suitcase illustrated in FIG. 7 through FIG. 9 .

In an embodiment, as illustrated in FIG. 10 , the multifunctional suitcase further includes a torsion spring 14 . The torsion spring 14 is disposed at the rotational connection position between the movable flap 4 and the case top cover 2 .

In the embodiment, the movable flap 4 is rotatably connected to the case top cover 2 through a hinge. A first hinge groove is defined on the movable flap 4 . A part of the hinge disposed on the movable flap 4 is disposed in the first hinge groove. A second hinge groove is defined on the case top cover 2 . A part of the hinge disposed on the case top cover 2 is disposed in the second hinge groove. In this way, the structure is simple, and rotation is convenient and stable. The hinge is disposed in the first hinge groove and the second hinge groove to avoid being exposed, therefore making the structure beautiful and avoiding being interfered by the external objects. The torsion spring 14 is disposed on the hinge. A disposition of the torsion spring 14 enables the movable flap 4 to tightly cling to the case top cover 2 in a natural state. The movable flap 4 will not loosen and does not affect the consignment. When the movable flap 4 is opened relative to the case top cover 2 to define the accommodation space, after articles are placed in the accommodating space, the movable flap 4 presses the articles between the case top cover 2 and the movable flap 4 to prevent the articles from falling.

It should be noted that, the movable flap (e.g., 4 , 4 ′, 4 ″) and the case top cover (e.g., 2 , 2 ′, or 2 ″) can alternatively be connected by a rotating shaft or other structures satisfying overturning of the movable flap (e.g., 4 , 4 ′, 4 ″).

In an embodiment, as illustrated in FIG. 8 , an upper end of the movable flap 4 ″ is provided with an outer flanging 401 . The outer flanging 401 is disposed at a side of the movable flap 4 ″ facing away from the telescopic pull rod 3 ″. In this way, when the movable flap 4 ″ is opened relative to the case top cover 2 ″ and the movable flap 4 ″ is used as a seat backrest, that is, a person sits on the case top cover 2 ″ and leans his or her back on the movable flap 4 ″, a design of the outer flanging 401 conforms to a sitting posture of a human body, so that the back is more comfortable and painless when being leaned on the upper end of the movable flap 4 ″.

In an embodiment, as illustrated in FIG. 4 through FIG. 6 , a handle 6 is disposed on the case top cover 2 ′. As illustrated in FIG. 1 through FIG. 6 , a hollowed hole (e.g., 7 , 7 ′) is defined on the movable flap 4 , 4 ′. The handle 6 is disposed corresponding to the hollowed hole 7 ′ and can be exposed through the hollowed hole 7 ′.

Specifically, reference character 7 refers to the hollowed hole of the multifunctional suitcase illustrated in FIG. 1 through FIG. 3 . Reference character 7 ′ refers to the hollowed hole of the multifunctional suitcase illustrated in FIG. 4 and FIG. 6 and the multifunctional suitcase illustrated in FIG. 5 .

In the embodiment, as illustrated in FIG. 4 through FIG. 6 , the hollowed hole 7 ′ is defined on the movable flap 4 ′ corresponding to the handle 6 disposed on the case top cover 2 ′. When the movable flap 4 ′ is rotated to be buckled relative to the case top cover 2 ′, the handle 6 disposed on the case top cover 2 ′ is exposed at the hollowed hole 7 ′, therefore not affecting people using the handle 6 .

In an embodiment, as illustrated in FIG. 4 through FIG. 6 , the movable flap 4 ′ is provided with a left barrier plate 8 on a left end of the movable flap 4 ′ and a right barrier plate 9 on a right end of movable flap 4 ′. The case body 1 further includes a left side surface 104 and a right side surface 105 . When the movable flap 4 ′ is rotated to be buckled relative to the case top cover 2 ′, the left barrier plate 8 is disposed at the left side surface 104 , and the right barrier plate 8 is disposed at the right side surface 105 . When the movable flap 4 ′ is rotated to be opened relative to the case top cover 2 ′, the movable flap 4 ′, the left barrier plate 8 and the right barrier plate 9 together define the accommodation space. The movable flap 4 ′, the left barrier plate 8 and the right barrier plate 9 together form a U-shaped enclosure, therefore more effectively preventing the articles on the case top cover 2 ′ from falling.

In an embodiment, as illustrated in FIG. 5 , the multifunctional suitcase further includes a pair of connecting reinforcement pieces. The left barrier plate 8 is connected to the left side surface 104 through one of the pair of connecting reinforcement pieces and the right barrier plate 9 is connected to the right side surface 105 through another one of the pair of connecting reinforcement pieces. Connecting the left barrier plate 8 and the right barrier plate 9 to the case body 1 can ensure stability and strength of a whole structure of the suitcase. It should be noted that, the pair of connecting reinforcement pieces have no interference on movement of the left barrier plate 8 and the right barrier plate 9 .

In the embodiment, as illustrated in FIG. 5 , the pair of connecting reinforcement pieces is a pair of connecting pieces 12 . Long holes 13 are defined on the pair of connecting pieces 12 . The pair of connecting pieces 12 are respectively rotatably connected to the left side surface 104 and the right side surface 105 . The left barrier plate 8 and the right barrier plate 9 are respectively hinged with the long holes 13 on the connecting pieces 12 . When the movable flap 4 ′ drives the left barrier plate 8 and the right barrier plate 9 to move, the pair of connecting pieces 12 cooperate with the movement of left barrier plate 8 and the right barrier plate 9 through the long holes 13 while rotating, so as to avoid jamming. The pair of connecting reinforcement pieces can further be made of foldable soft materials, such as two ropes or two pieces of cloth, as long as requirements are met.

In an embodiment, as illustrated in FIG. 7 through FIG. 9 , the movable flap 4 ″ includes a connecting part 10 and a backrest part 11 . A lower end of the connecting part 10 is rotatably connected to the front end of the case top cover 2 ″. The backrest part 11 is rotatably connected to an upper end of the connecting part 10 , so that the backrest 11 can automatically adjust an angle according to a leaning state of the human body to conform to the sitting posture and ergonomics of the human body. The backrest 11 can rotate to fit a waist of the human body and fully support the waist of the human body, so as to relieve waist fatigue during the journey. It should be noted that, a rotational connection between the connecting part 10 and the case top cover 2 ″ has a rotation limit, and a rotational connection between the backrest part 11 and the connecting part 10 has a rotation limit.

In the embodiment, a shape of the backrest part 11 can be a U-shape or a flat, as long as requirements are met.
